3m-5 = 7-21 3m = 7-21+5 3m = -9 m = -3
m = 3
Well, 3m + m = 4m so 88 divided by 4= 22 there fore m =22 and 3m = 66
x=28
m = 12. 3 x 12 = 36, 36 + 8 = 44.
3m-5 = 7-21 3m = 7-21+5 3m = -9 m = -3
Add 12 to each side: 3m = 6; m = 2
m = 3
3m + 9 = 36subtract 9 from both sides3m = 27divide both sides by 3m = 27/3 = 9
Well, 3m + m = 4m so 88 divided by 4= 22 there fore m =22 and 3m = 66
x=28
I'm an orange!
m2-3m=-1 => m2-3m+1=0 Delta = (-3)2 - 4 * 1 * 1 = 5 m = (3 + sqrt(5)) / 2 or m = (3 - sqrt(5)) / 2
A is 14
9m + 9m + 3m + 3m = 24m
If: 3m = 78 Then: m = 26
m + m + m
